Hello! The past couple days, I've noticed that one of my hens has started pecking at another hen, around the face. The hen that is being pecked at was being broody, and I'm still trying to break that. They're about the same size and appearance. It is pretty cold where I live, so I've had them inside more than usual. The coop dimensions are roughly about 5 by 6 (feet). This worries me because whenever I try to get the hen to move out of the box to get some food/water, she gets pecked at. Does anyone know what's going on, and/or how to stop it? Thanks!
